SD card not working in SD slot

I just bought a new SD card (Core Micro SD-2 GB)and it doesn't seem to work in the SD slot in my computer. It worked with the my other SD card that I had (Kodak-256MB). When I try to transfer pictures from the card to the computer it does not read the card. What could be the problem?

It could be that the card reader was based on an earlier specification of the SD format than your new 2 GB card. See this article at wikipedia that discusses compatibility issues with 2 GB (and up) SD cards:http://en.wikipedia.org/wiki/S.....rger_cards

So your telling me there is no way to fix this? This is very frustrating because when I hook up my camera to the computer it can not find a device driver or when it tries to install it, it fails. So my only way to put my pictures on the computer now is to insert the SD card into the SD slot. It says "Windows found driver software but encountered an error while attempted to install it.....the driver installation file for this device is missing a necesary entry. This may be because the INF was written for Windows 95 or later. Contact your hardware vendor." It has worked before so I do not know what may have happened.

Thunder, there are two things that we would like to know. First, which SD card specifications are handled by the SD card reader in your system? Second, which SD card specification was the 2 GB CoreMicro card built for? You may never know the first, because these card readers are so generic, but you could ask the manufacturer of the system. For the 2nd question, you should contact CoreMicro -- in other words, take the advice of the error message and contact some hardware vendors! CoreMicro is here:http://www.coremicro.ca/

As for the error message that you are getting, you could try uninstalling the SD card in Device Management. Press Win+R for a run box, then type in "devmgmt.msc". The SD card should have a yellow ? or red X by it because the driver didn't install. Find the SD card, right-click on it, and select "Uninstall". Then restart your computer and it will reinstall. You might also check at CoreMicro to see if they have an updated driver.

One more thing. If you decide to purchase a new card reader, I would *strongly* suggest that you get one that is certified for SDHC. This stands for SD "High Capacity" and is used for all cards 4 GB and larger. SDHC is the common name for the SD version 2.0 specification. This v2.0 specification provides backwards compatibility with earlier ones. You would not want to buy a new card reader today, then a few months later purchase a 4+ GB SDHC card only to find that your "new" reader can't read this and you need to purchase yet another reader.
